Abstract: The present invention relates to a system for monitoring a switchgear. The system comprises:
- an infrared camera;
- a processing unit; and
- an output unit.
The infrared camera is configured to acquire a first infrared image of the switchgear, and a total number of pixels in the first infrared image is equal to a first number. The processing unit is configured to determine a pixel in the first infrared image with a maximum temperature in the first infrared image. The processing unit is configured to utilize a second number of pixels less than the first number of pixels to determine a temperature interval for the first infrared image equal to a difference between the maximum temperature in the first infrared image and a threshold temperature in the first infrared image. The processing unit is configured to sort the pixels in the infrared image in descending order of temperature from the maximum temperature and determine the threshold temperature in the first infrared image as a temperature of a pixel in the first infrared image that is the pixel placed a set number in the sorted order of pixels in the descending order of temperature from the maximum temperature, and the set number is equal to the second number of pixels. The processing unit is configured to determine that a hot spot exists in the switchgear. The determination that the hot spot exists comprises utilization of the temperature interval for the first infrared image. The output unit is configured to output an indication of a fault in the switchgear when the determination has been made that a hot spot exists in the switchgear.
